Rationale: Clients with an alteration in the CYP2C19 gene do not metabolize warfarin (Coumadin) well, leading to higher blood levels and more side effects.

This device helps prevent blood clots from reaching the lungs, reducing the risk of pulmonary embolism.

Correct Answer: B

Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.
